Two burst water mains caused loss of water supplies to some properties in Morecambe and Heysham over the weekend.
United Utilities said the problems started on Saturday when a 15 inch water main burst but this was then resolved.
On Sunday there were further problems when a 12 inch water main burst, causing disruption to supplies again.
A spokesman for United Utilities said: “The areas affected were Balmoral Road, Heysham, Middleton and houses in the LA2 and LA3 areas.
“We brought a water supply in through other pipes and maintained supplies to Heysham 1 and Heysham 2.
“The water supplies were on and off at various times over the weekend.
“Some customers supplies were interrupted and we would apologise for that.”
